A method for producing galanthamine using a plant, includes (a) performing a thermal treatment on a living plant to induce accumulation of galanthamine therein, wherein the living plant is a plant belonging to the family Amaryllidaceae; and (b) placing the living plant in a medium and performing an electrical stimulation treatment on the living plant to release the galanthamine from the living plant to the medium.

A method for promoting the accumulation of secondary metabolites of cannabis is disclosed. The method comprises the step of adding a green-yellow light, which has a peak wavelength at 506-571 nm, into the indoor growing environment for cannabis, and maintaining the light intensity and other growth conditions, to improve the content of secondary metabolites. The production of secondary metabolites of cannabis can be increased by up to 18%.

The present disclosure relates to the field of algal cultivation and biofuels. Particularly, the present disclosure relates to a method of enhancing lipid production during algal culturing. Particularly, the present disclosure relates to a method of enhancing neutral lipid and total lipid production by maintaining algae in a thin layer cultivation system and exposing said algae maintained in the thin layer cultivation system to infra-red (IR) radiation. Said method enhances lipid accumulation in algae, thereby increasing the yield of neutral lipids and total lipids. The method is simple, cost-effective in producing high quantities of algal-derived biofuels, requires shorter time duration for lipid induction and results in no or minimal reduction of biomass.

Various embodiments disclosed relate to increasing the proportion of omega-3 fatty acid in seed oil produced by a plurality of Brassica plants, such as canola, transgenically modified to produce seed oil comprising at least one of EPA, DHA and DPA. Transgenic Brassica plants, such as transgenic canola, are subjected to an environment which has an average daily day-night temperature difference of at least 13° C. during the transgenic plant's period of seed maturation. The seed oil is at least 5 wt % EPA. The seed oil is at least 1 wt % DPA. The seed oil is at least 0.2 wt % DHA. The seed oil is at least 5.2 wt % a mixture of EPA and DHA. The seed oil is at least 6 wt % long chain omega-3 fatty acids.

The present invention relates to a method for producing Cannabis sativa L. seed, and more particularly, to a method for producing Cannabis sativa L. seed for efficiently cultivating a low-narcotic Cannabis variety, and when Cannabis sativa L. seeds produced by the production method are used, it is possible to cultivate Cannabis female plants where female flowers are formed, and it is possible to improve the quantity of Cannabis female flowers. Further, when a Cannabis extract is prepared using the Cannabis female flowers, it is possible to prepare a low-narcotic Cannabis extract.

A light source for plant cultivation and a plant cultivation method are provided. The plant cultivation method includes planting germinated seeds of a plant; and growing the plant by applying light treatment to the plant. In growing the plant, main light treatment of supplying main light to the plant and dark treatment of cutting off supply of the main light to the plant are alternated. The main light has at least two peak wavelengths in the visible light spectrum. In addition, the main light has a PPFD of greater than 92 mol/m.sub.2/s to less than 198 mol/m.sup.2/s.

Processes for the production of large quantities of diploid F1 Solanum potato tubers that are uniform in shape are provided. Diploid F1 hybrid plants are produced from true seeds. The tubers produced by the diploid F1 hybrid plants are either harvested for consumption, processing or extraction, or for production of seedling tubers which are then planted to produce tubers for consumption, processing or extraction. Also provided are diploid F1 hybrid seeds and plants that produce large quantities of tubers that are uniform in shape and produce large quantities of sprouts per tuber when used as seedling tubers.
